Bonnie Rotten is known for pushing the envelope in the world of adult entertainment. Today, she's taking a girl's day in and making it extra fun! She's got nine girls ready to show they've got what it takes to survive her "Sybian Showdown". They will be judged on how long they can sit on this "bucking bronco" while the other girls slap, tickle, lick and tease them to orgasm! Who will win the Sybian challenge? It may be the "tiny terror", Piper Perri or the sultry Selma Sins! Either way…these girls are having good times with these good vibrations!
